A redesigned Profile Account card: a clear Sign in / Create account switch, the username field only when creating an account, and a sign out you can't miss. Three iterations in — open it and try all three states.

A map at the very top of Discover with a full-screen option: pins for rated shops only, a simulated "you are here," and nearest-shop distances — while home-made coffees never create pins or counts. Fictional Huntington, NY shops on fake data; the design for the real App Store build is in the prototype folder's FINDINGS.md.

A Discover view for new places: browse a town where nobody you know has rated a shop and the shops show a community average — one average per shop across everyone, aggregates only, and only once a shop has 3+ ratings. Four fictional towns cover the travel case, home turf, mixed, and the sparse early-days case.

The full reset flow behind the sign-in card's "Forgot password?" link: request a link, check your email, set a new password — plus the expired-link screen and an honest look at the plain system email that actually arrives. Three iterations in — walk it end to end, including an hour later.
